Special Issue Information

Dear Colleagues,

The advances of precision micromachining have promoted the development of miniaturized functional components and devices for high-tech industrial products. To develop new principles-based micromachining techniques and to further improve existing processes, technologies with higher precision or efficiency are still essential for meeting the increasingly growing requirements of the industry, especially for hard-to-machine materials. The trend from micromachining to nanofabrication has also received extensive attention, and nanostructured components will certainly play a more important role in the development of high-value industrial products. Among the techniques for nanofabrication, the development of maskless, large-area, super-resolution and high-efficiency techniques is critically challenging.

In this Special Issue, we call for papers in ultraprecision micromachining and nanofabrication that contribute to the advances of new principles, mechanisms and methods. Original research papers, review articles, and short communications are all welcome.

Nodular cast iron QT700-2 is extensively used in automobile engine crankshaft parts due to its prime mechanical properties. The journal of a crankshaft is a curved surface, and traditional wheel grinding easily causes grinding burn and surface and subsurface damage. Shape adaptive grinding (SAG) is a flexible grinding technology, which has the advantages of low grinding force and temperature, and good grinding quality. It is suitable for machining curved surface parts with complex shapes. Therefore, the SAG surface integrity of nodular cast iron QT700-2 was experimentally investigated. The influence of grinding parameters on grinding force, material removal rate, grinding temperature, and surface integrity was studied, and the machining performance of SAG tools was evaluated. It was concluded that the grain size in SAG is the most important factor affecting the grinding force, material removal rate, and surface roughness; the influence of SAG grinding is very weak, mainly removing the workpiece material. Then, the influence law of SAG technology on the surface integrity of nodular cast iron QT700-2 was summarized, and the optimal grinding parameters were obtained, providing a reference for the curved surface grinding of nodular cast iron QT700-2 in the future.
